* DT bindings for Renesas R-Car Gen3 Thermal Sensor driver
2
-
3
-
On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
4
-
sensors (THS) which are the analog circuits for measuring temperature (Tj)
5
-
inside the LSI.
6
-
7
-
Required properties:
8
-
- compatible : "renesas,<soctype>-thermal",
9
-
Examples with soctypes are:
10
-
- "renesas,r8a774a1-thermal" (RZ/G2M)
11
-
- "renesas,r8a774b1-thermal" (RZ/G2N)
12
-
- "renesas,r8a7795-thermal" (R-Car H3)
13
-
- "renesas,r8a7796-thermal" (R-Car M3-W)
14
-
- "renesas,r8a77961-thermal" (R-Car M3-W+)
15
-
- "renesas,r8a77965-thermal" (R-Car M3-N)
16
-
- "renesas,r8a77980-thermal" (R-Car V3H)
17
-
- reg : Address ranges of the thermal registers. Each sensor
18
-
needs one address range. Sorting must be done in
19
-
increasing order according to datasheet, i.e.
20
-
TSC1, TSC2, ...
21
-
- clocks : Must contain a reference to the functional clock.
22
-
- #thermal-sensor-cells : must be <1>.
23
-
24
-
Optional properties:
25
-
26
-
- interrupts : interrupts routed to the TSC (must be 3).
27
-
- power-domain : Must contain a reference to the power domain. This
28
-
property is mandatory if the thermal sensor instance
29
-
is part of a controllable power domain.
